Re: LiveCD Problems

:Additionally, I noticed a get a livelock message quite frequently on 
:'intr 5' limiting it to 20000hz because it's usually at 96xxxhz.

    What's on interrupt 5?  vmstat -i and/or the saved dmesg output
    (/var/run/dmesg.boot) should tell you.

    It's quite possible for firewire or GigE to generate more then
    50,000 interrupts/sec.  I definitely need to adjust the
    default based on available cpu power or perhaps even on % cpu
    use by the interrupt in question.  The code in there now is a
    stopgap to 'save' the machine from interrupt related lockups.
    The limits can be increased with a sysctl but you should first
    make sure that the interrupt rate is legitimate.

:Additionally, I have two CD drives and noticed that I can only boot from 
:the 1st once successfully. Trying to boot from the second one causes a 
:panic trying to mount the root file system.
:
:Any way I can help you figure out why the first problem is occurring?

    I will add a second CD on my secondary slave and try to reproduce
    the problem.
